This study was performed to verify various effects of 70% ethanol extract and distilled water extract of pine leaf such as antioxidant, anti-inflammatory, skin-lightening effects analysis in cells. The result of antioxidant experiment showed that polyphenol content increased concentration dependently in polyphenol and flavonoid effects. The total content of polyphenols and flavonoids was much higher in ethanol extract than water extract. In all the cells of B16F10, RAW264.7 cytotoxicity at each concentration level didn't appear. The result of measuring NO production inhibition showed that it inhibited NO production led to LPS effectively, so anti-inflammatory activity was confirmed. The result of measuring melanin biosynthesis inhibition showed that there was considerably reduction effect, but it performed western blot, and as a result of MITF, Tyrosinase protein revelation, the inhibition of MITF, Tyrosinase revelation was confirmed concentration dependently, Therefore, in this study pine leaf extract was expected to be used as a cosmetic ingredient.

1. King Hyeonjong(1641-1674) mainly suffered from eye disease and abscess. He specially took a hot spring bath for cure of eye and skin problems. He probably died of septicemia and the following gastro-intestinal infection at the age of 34, quite early for his age. 2. King Sukjong(1661-1720) was not very well all through his life, but lived quite longer than other Kings in the Joseon Dynasty. He suffered from various diseases like heart-based heat, abscess, edema, upper respiratory infections, etc. He frequently took the treatments of acupuncture and moxibustion. He presumably died of dysfunction of liver and kidney at the age of 60. 3. King Gyeongjong(1688-1724) suffered from political problems from birth to death, so he may have had excessive mental stress for his poor health. He mainly suffered from heart-based heat and abscess. It is quite not sure why he died in only one month from the onset of his symptoms, so many people thought that he was poisoned to death. He probably died of septicemia and the following gastro-intestinal infection at the age of 37. 4. King Yeongjo(1694-1776) lived for 83 years, which is the longest of all the Kings in the Joseon Dynasty. He mainly suffered from hypofunction of gastro-intestinal system with cold symptoms, coughs, uneasiness. He took various kinds of herbal medicine, of which he took ginseng the most. He is supposed to be dead due to his old age at 83.

Linoleic acid [LA; 18: 2 (n-6)] is the most abundant polyunsaturated fatty acid in human skin. The exclusion of LA from diet induces epidermal hyperproliferation, which is reversible by the inclusion of LA in diet, and hence, LA is heralded as an essential fatty acid (EFA). Since safflower oil (SO) has been widely recognized as the major dietary source of LA and Arctii Fructus (Arctium lappa L.) is recently reported to contain high level of LA, we compared the antiproliferative effects of SO and Arctii Fructus in this study. Epidermal hyperproliferation was induced in guinea pigs by hydrogenated coconut oil (HCO) diet for 8 wk. During following 2 wk, EFA deficient guinea pigs were fed diets of safflower oil (group HS), water extract of Arctii Fructus (group AW) or organic extract of Arctii Fructus (group AO). Normal control group was fed SO containing diet (group SO) and EFA deficient group was fed HCO containing diet (group HCO) for 10 wk. Epidermal hyperproliferation was reversed in groups AO (55.9% of group HCO) and HS(74.1% of group HCO). However, the thymidine incorporation into epidermal DNA of group HS was greater than of normal control group SO. Epidermal hyperproliferation was not reversed in group AW. The accumulations of LA into phospholipids and ceramides, and of 13-hydroxyoctadecadienoic acid (13-HODE), the potent antiproliferative metabolite of LA in the epidermis of group AO were greater than of group HS. In contrast, the de novo synthesis of ceramides, the major lipids maintaining epidermal barrier, did not differ between all of groups. Together, our data demonstrate that organic extract of Arctii Fructus is more prominent than safflower oil in reversing epidermal hyperproliferation by inducing the higher accumulations of LA and 13-HODE in the epidermis of guinea pigs.

Background: Cancer constitutes a key pressure on public health regardless of the economy state in different countries. As a kind of highly malignant epithelial tumor, lacrimal gland adenoid cystic carcinoma can occur in any part of the body, such as salivary gland, submandibular gland, trachea, lung, breast, skin and lacrimal gland. Chemotherapy is one of the key treatment techniques, but drug resistance, especially MDR, seriously blunts its effects. As an element of the 60S large ribosomal subunit, the ribosomal protein L39-L gene appears to be documented specifically in the human testis and many human cancer samples of different origins. Materials and Methods: Total RNA of cultured drug-resistant and susceptible lacrimal gland adenoid cystic carcinoma cells was seperated, and real time quantitative RT-PCR were used to reveal transcription differences between amycin resistant and susceptible strains of lacrimal gland adenoid cystic carcinoma cells. Viability assays were used to present the amycin resistance difference in a RPL39-L transfected lacrimal gland adenoid cystic carcinoma cell line as compared to control vector and null-transfected lacrimal gland adenoid cystic carcinoma cell lines. Results: The ribosomal protein L39-L transcription level was 6.5-fold higher in the drug-resistant human lacrimal gland adenoid cystic carcinoma cell line than in the susceptible cell line by quantitative RT-PCR analysis. The ribosomal protein L39-L transfected cells revealed enhanced drug resistance compared to plasmid vector-transfected or null-transfected cells as determined by methyl tritiated thymidine (3H-TdR) incorporation. Conclusions: The ribosomal protein L39-L gene could possibly have influence on the drug resistance mechanism of lacrimal gland adenoid cystic carcinoma cells.

Lactic acid bacteria (LAB) have beneficial effects on intestinal health and skin diseases. Lipoteichoic acid (LTA), a cell wall component of gram-positive bacteria, is known to induce the production of several cytokines such as TNF-α, IL-1β, and IL-8 and affect the intestinal microflora, anti-aging, sepsis, and cholesterol level. In this study, Weissella cibaria was isolated from Indian dairy products, and we examined its immune-enhancing effects. Live and heat-killed W. cibaria did not induce the secretion of immune-related cytokines, whereas LTA isolated from W. cibaria (cLTA) significantly increased the secretion of TNF-α, IL-1β, and IL-6 in a dose-dependent manner. cLTA increased the phosphorylation of nuclear factor kappa-light-chain-enhancer of activated B cells, p38 mitogen-activated protein kinases, and c-Jun N-terminal kinases in THP-1 cells. The secretion of TNF-α and IL-6 was also increased in the cLTA-treated mouse splenocytes. These results suggest that cLTA, but not W. cibaria whole cells, has immune-boosting potential and can be used to treat immunosuppression diseases.

To evaluate long-term metabolic response of free-living Korean subjects consuming local sources adequately or slightly below habitual intake. Subjects, six male medical students aged 23-25 years were free-living, but consumed diets in the metabolic unit. They were healthy as determined from medical laborarory tests. They belong to the Korean middle-class. Temperature of outdoor during study were ranged between -2 to $26^{\circ}C$, whereas the indoor were $18-22^{\circ}C$. Animal protein ranged between 25-30% of total calorie. The three meals and a vitamin supplement to meet recommendation were given daily. Three 50day periods following the design were used to test the protein-energy adequacy of the diet. Urinary nitrogen excretion was measured daily. Fecal samples were pooled for the last 5 days of each week. Nitrogen balance was computed using 5mg N/Kg skin and miscellaneous losses. Body weight was measured daily. The study was covered on 126 metabolic observations weekly. Body weight changes were relatively stable with the energy intake of 37-44Kca1/kg, and N-balances were also relatively stable, but it was influenced by physical and or mental stress somehow. It could be assumed that the mean protein and energy requirement were $190{\pm}10mg$ N/Kg with $41{\pm}2$ Kcal/kg, and the mean digestibility of protein was 81% on these subjects with the experimental conditions. The protein requirement, however, could be cut down somewhat with some limited increaing of energy intake under parameters of N-balance and maintaining body weight. It was also observed a tendency of the requirement were getting smaller with the increase of body size.

Recently plant extracts have obtained increased attention because of their health-related beneficial aspects. In this study, we evaluated anti-oxidation, whitening and anti-wrinkle of four different extracts obtained from Rubus coreanus (ethanol extracts of unripe, ripe fruits, leaves/stems, and roots). The ethanol extract of unripe fruits of Rubus coreanus generally showed stronger whitening and the anti-wrinkle activities than other extracts of Rubus coreanus. As a results, we knew that the ethanol extract of unripe Rubus coreanus fruit had mote possibility as a whitening and anti-wrinkle ingredient for skin care products.

Nypa fruticans wurmb (NF) has been used as traditional medicinal food in Asian countries. Especially, NF has been used for conventional medicine to treat inflammatory periodontal diseases. Previous studies have been shown that NF has large amount of useful constituents such as phenolic acids, polyphenols and flavonoids. Also, NF is known as having medicinal effects such as anti-oxidant, anti-inflammatory and cholesterol-lowering effects. NF has recently been attracted to use complementary medicinal food on inflammatory diseases in Korea. However, there are no obvious effects in inflammatory and metabolic diseases also mechanisms has been studied yet. The purpose of this study was to investigate the anti-inflammatory effects of NF and steamed-NF (SNF), which recently has been used as health food, using Human keratinocyte cell line (HaCaT) and Human mast cell line (HMC-1). The cytotoxicities of NF and SNF were measured by using MTT assays in HaCaT cells and HMC-1 cell. To evaluate anti-inflammatory effects of NF and SNF, HaCaT cells were stimulated with tumor necrosis factor $(TNF)-{\alpha}$ and Interferon $(IFN)-{\gamma}$. Also, HMC-1 cells were stimulated with phorbol-12-myristate-13-acetate (PMA) and A23187 calcium ionophore (A23187) to induce allergic inflammation. Inflammatory cytokine were measured by enzyme-linked immunosorbent assay (ELISA). In this result, the extract of NF and SNF (0.01 - 1mg/ml) did not show cytotoxicity in HaCaT cells and HMC-1 cells. In addition, the NF and SNF suppressed the production of interleukin (IL)-6 and IL-8 in HaCaT cells at highest concentration. Furthermore, the treatment of SNF significantly inhibited the secretion level of IL-8 in PMA plus A23187-stimulated HMC-1 cells compared with NF treatment group. These results suggest that the extract of NF and SNF may serve as a potential therapy for skin inflammatory diseases.

Bioconversion, the enzymatic process by microorganism on organic precursor to desired products. The natural extract is converted into a form that can be easily absorbed into the skin, while scaling up of to higher quantity is possible. Selection of naturally processed raw material rather than chemically processed is preferred. Therefore, fermentation was carried out by mixing Rubus coreanus Miquel, soybean, Zanthoxylum schinifolium as bioconverting materials, the possibility of inflammation, whitening material were checked. In this study, useful microorganisms were isolated from various salted fish, and 16S rDNA sequence was analyzed to confirm their genetic characteristics. Combining the three natural materials using bioconversion technology to study their activity before and after fermentation. To evaluate the antioxidant activity and the active ingredient content the DPPH radical scavenging activity and the total polyphenol content were examined. Raw 264.7 cells were used to evaluate MTT assay, NO and $TNF-{\alpha}$ production inhibitory activity. Also, to evaluate the whitening activity, tyrosinase inhibitory activity and melanin formation inhibitory activity were measured using B16F10 cells. In total 34 strains were obtained from various salted fish. The effective strains useful for the bioconversion process, showed that DPPH radical scavenging ability and polyphenol content were increased in the two kinds of microbial treatment groups compared to the untreated group. 16S rDNA sequencing analysis of the strains showed excellent in Pediococcus pentosaceus B1 in comparison. An increase of up-to 156% in anti-oxidative activity and 141% in polyphenol content was observed after bioconversion. In addition, after mixed fermentation the toxidty of Raw 264.7 and B16F10 cells tended to decrease and a significant increase was observed in anti-inflammatory activity as well. Also, tyrosinase activity and melanin significantly. synthesis decreased significantly.

Background: Cancer has become a major health problem associated with high mortality worldwide, especially in developing countries. The aim of our study was to evaluate the incidence rates of different types of cancer in Sulaymaniyah from January-2006 to January-2014. The data were compared with those reported for other middle east countries. Materials and Methods: This retrospective study depended on data collected from Hiwa hospital cancer registry unit, death records and histopathology reports in all Sulaymaniyah teaching hospitals, using international classification of diseases. Results: A total of 8,031 cases were registered during the eight year period, the annual incidence rate in all age groups rose from 38 to 61.7 cases/100,000 population/year, with averages over 50 in males and 50.7 in females. The male to female ratio in all age groups were 0.98, while in the pediatric age group it was 1.33. The hematological malignancies in all age groups accounted for 20% but in the pediatric group around half of all cancer cases. Pediatric cancers were occluding 7% of total cancers with rates of 10.3 in boys and 8.7 in girls. The commonest malignancies by primary site were leukemia, lymphoma, brain, kidney and bone. In males in all age groups they were lung, leukaemia, lymphoma, colorectal, prostate, bladder, brain, stomach, carcinoma of unknown primary (CUP) and skin, while in females they were breast, leukaemia, lymphoma, colorectal, ovary, lung, brain, CUP, and stomach. Most cancers were increased with increasing age except breast cancer where decrease was noted in older ages. High mortality rates were found with leukemia, lung, lymphoma, colorectal, breast and stomach cancers. Conclusions: We here found an increase in annual cancer incidence rates across the period of study, because of increase of cancer with age and higher rates of hematological malignancies. Our study is valuable for Kurdistan and Iraq because it provides more accurate data about the exact patterns of cancer and mortality in our region.
